Teenagers from Tasmanian migrant families are doing better at school as a result of a migrant tutoring program.

Three times a week, 20 high school and college students are helped by volunteer tutors at the Launceston Migrant Resource Centre.

The program is growing and the centre is now looking for more tutors.

The centre's case worker Senka Mujkic came up with the program after being repeatedly asked for help with school work.

Ms Mujkic says it is the first of its kind in Tasmania and is working well for the students.

"One of the girls came up to me and she said 'Look Senka I've passed, I've passed' and she had gone from basically a fail to getting Bs," she said.

"That's extreme to me and it's just so nice to see them being able to complete something."

Year 11 student Diria Luate says the extra help is making a big difference to her school results.

"I'm one of those people that find it difficult to kind of step forward when you struggle and so it's good to have that one-on-one talk with someone and even my teacher noticed a dramatic change," she said.

Volunteer Tom Hardy hopes other programs will start up to support non-migrant students as well.

"There's lots of retired folks like myself that have lots of talent."

As demand grows the centre will need more tutors and funding for a bigger classroom.
